One year ago, Michael Cohen, Donald Trump’s longtime lawyer and fixer, pledged he “would take a bullet for the president.”

On Tuesday, that once-deep loyalty melted away when Cohen stunningly implicated the U.S. president in two felony crimes as he pleaded guilty to charges of bank fraud, tax fraud and campaign finance violations.

It was a huge takedown for the brash New Yorker, who tied the last decade of his career personally to Trump.
